Komatsu Galeo PC27MR-2 Operation & Maintence Manual page 170

MAINTENANCE
If the coolant level is low, it will cause overheating, and will also cause problems with corrosion due to air entering
the coolant.
Grease
Grease is used to prevent seizure and noises at the joints.
This construction equipment is used under heavy-duty conditions. Always use the recommended grease and
follow the change intervals and recommended ambient temperatures given in this Operation and Maintenance
Manual.
The nipples not included in the maintenance section are nipples for overhaul, so they do not need grease.
If any part becomes stiff after being used for long time, add grease.
Always wipe off all of the old grease that is pushed out when greasing.
Be particularly careful to wipe off the old grease in places where sand or dirt sticking in the grease would cause
wear of the rotating parts.
Carrying Out KOWA (Komatsu Oil Wear Analysis)
The oil clinic samples the oil periodically and analyzes it. This is a preventive maintenance service, which provides
early discovery of abnormal parts and wear of the drive parts of the machine. This then makes it possible to ensure
prevention of failures and reduction in downtime.
Komatsu's long years of experience and rich supply of accumulated data make it possible to accurately determine
the condition of your machine. This enables us to locate the problems and to recommend suitable and timely repair
methods.
The oil clinic charges the customer only the actual costs, and provides an immediate report of the results of the
analysis and recommendations for action to take. This low-cost service can save you high costs and inconvenience
in the future, so we strongly recommend you to avail yourself of this service.
KOWA Analysis Items
Measurement of density of metal wear particles
This uses an ICP (Inductively Coupled Plasma) analyzer to
measure the density of iron, copper, and other metal wear
particles in the oil.
Measurement of quantity of particles
This uses a particle quantifier index measurement machine to
measure the quantity of iron particles of 5µ or more, enabling
early detection of failures.
Others
Measurements are made of items such as the ratio of water in the oil, density of the antifreeze coolant, ratio of
fuel in the oil, and dynamic viscosity, enabling a highly precise diagnosis of the machine's health.
